CARZUNDERFRAME Specicetion of Letters Patent.

Patented April 28, 1908.

Application filed November 22, 1907. Serial No. 403,370;

To all whom it may conci/m:

Be it known that l', WiLLiAM Meliv'rosn, e. citizen ofthe United States, residing at North Plainfield, in the county of Somerset land State oi' New Jersey, have invented zi new und useful improvement inCer-Underfrsines, of which the following is s specification.

My invention relates particularly to the end sills of metallic ein' uiulerlranie, und has for its object to provide e. strong, rigid, end durable end sill specially adapted. to reinforce and prevent hiterlrl displacement of the iniddle And side longitudinal sills at the attachment oi their end portions thereto, and to strengthen the end sill therest.

g it consists in features of novelty :is hereinafter described end claimed, reference being hed to the accompanying drawing forming pel't of this specilieetion, whereon,

Figure 1 is a to plan view of iny improved end sill es applis( to the end portions of the middle ond side longitudinal sills of a metallic csr underfrsxne; Fig, 2 is u front elevation thereof; Fig. 3, en end view of the end sill with the end portion of thev corresponding side longitudinal sill ritt ached thereto, in side elevation, Fig. 4, e vertical transverse section through the end sill on line 4, 4, in Fig. 1, with the end portionfof one of the middle longitudinal i sills attached thereto, in side elevation, and 5, e. horizontal section through the end, sill and end portions of the middle longitudinal sills on line 5, 5, in Fig. 2.

Like letters and numerels of reference denote like parts in all the figures.

(L represents iny improved. end 'sill which is preferably composed of cast steel channelshsped in cross section, und in the present divided transversely into n middle party 1, and two end ports l". fixed together et an equal distance from the longitudinal center oi' the can' uinlerfrniue, by splicing end rivets 2, es shown, or in any other suits-ble manner. Or the end sill muy he integral throughout, its web 3 being'urrmiged vertitically outward and' its to lsind bottoni flanges 4 sind 5, respectively, inward, the to i flange 4 being nreferebly wider and extentiing rearward beyond the bottoni flange 5, and the middle bert 1 of the sill a orojecting preferably forwerd beyond the enr parts 1. Gr the sill d indy be othV shaped in cross section lr member und top und bottoni. l' projecting rearward ther i, nie eli-oni.

-web 3, between the flanges 4 and 5 adjacent to the end piece 6 rprojects s horizontal rib 7. liveted to the inner face of the end piece 6 between the top and bottoni flanges 4, 5, and rejecting rearwardly therefrom for a suita'lile distance, is e splice-plate 8,-heving its projecting portion bearing against the inner faceof the upright web 9 of the corresponding side-i longitudinal sill b, which is preferably, channel-shaped in cross section, the web 9 preferably butting endwise a einst therear odge of the end piece 6, and to t 1e rib 7 of the end sill/o is riveted a gusset-plate 1t) having a lateral flange 10 bearing against the inner face ofthe splice-plate 8, the web 9 of 'the side sill b, splice-plate 8, and flange 10', being firmly fixed together by rivets 1l, whereby the end ortionI of the side sill b is firmly secured to t e end piece 6, and furtherinore braced. to the web 3 of the end sill a, by the gussetlate 10, to which is also riveted the end of tlie diagonal brace 12 (indicated by `dotted lines in Fig. 1) between the end sill a thereat and the body-bolster or equivalent member (not shown) of the underfra-ine, the whole forming a strong and rigid reinforcement of the end and side sills L and l) for resisting shock ther-eat. If desired the web 9 of the side sill b, in lieu of butting against the rear edge of the end piece 6 as described, may be extended and bear ageinstlthe insidel face thereof and the splice-plate '8 omitted, in which case the flange 10 of the gussetlate' 10 is riveted directly to the web 9 an end l piece 6.

Projecting rearwerdly from and integrl with the web 3' of the. end sill (L, between the flanges 4 and 5 and at right angles thereto, at e suitable and equal distance on erich side of the longitudinal center of the underfrarne, is :t rib or bracket 13 which is preferably integral with the, middle part 1 of the vend sill a, the ribs A13 being united to each other .by a horizontal web 14en'd the end sill a otherwise adapted interinediately Ito the ribs 13 beneath the web 14, for the passage and play therethrough of the coupler draw-bartnotl shown),the recess 15 for the latter in the.'

underside and body of the sill a being closed cy the drew-bar carry-iron 16 which is prefersbiy luf-snarled in cross section endxedto the underside of the bottom ilange 5 of the silla adjacent to the recess 15 by bolts 17, the middle portion of the carry-iron 16 project.- in upward into the recess and strength,- ening the sill a thereat.

AThe middle longitudinal sills c of the underframe consist respectively, in the )resen't case of an upright plate or web 18 wliicli bears at its end portion against one side ol the corresponding rib 13 to which it is fixed by rivets 19, the plate 18 having a top angle iron 2O riveted thereto, and a bottom flange y,21 which is lixed to the bottom flange 5 of the sill a preferably, by one of the bolts 17 of the carry-iron 16 (or otherwise) whereby -the middle longitudinal sills c are firmly secured to the end sill a and prevented by the ribs 13 from lateral displacement. ln this construction the end sill is greatly strengthened at its weakest oints by the extended attachinents of the ongitudinal sills thereto combined with the gusset bracings between its web or upright imember and the side longitudinal. sills, and `with the diagonal i bracing of these gusset braces to the inter mediate transverse members, such as the body-holsters or their equivalents, of the underframe.

What l claim as my invention and desire to secure by Letters Patent is:
